Anyone know where to get a replacement ?

Or if any other GM crosses over? Caddy, Buick, Chevy?

I think you're going to have to find a good used one or try to rebuild your existing unit.

This company can probably rebuild yours for you http://www.mykmlifestyle.com/

I have read that the 67 Cadillac ElDorado sender will work just fine.

Hi,
Me too, it seems that this one is working if the comments are right :

Let me know, I might need it too if mine is not easily repairable...

Thanks all!

The 67 Eldo sender looks the same. I think I’ll try it and see.

Mine works right now but it’s pretty rusty. I dropped the tank to empty it. Gas has been sitting in it four over four years and has turned to varnish. Damn that stuff stinks!

Figured I’d replace it and keep this one for a backup. I’ll have to store it in a sealed ziplock tho to keep the stink out of my shop. Thanks US Government!

Is it the ethanol residue that's stinking?

I believe it’s the additives the govt demands they put in the gasoline. The ethanol evaporates quickly and then what’s left starts to deteriorate.

I’ve worked on cars since I was a kid. Back in the 70’s. We could take old cars that had been sitting for years and revive them. The old gas that was left in them had a unique smell. It was like...well...old gas. It actually smelled good to me. And it would burn in the engine without gumming up the carb.

This new stuff is awful! Smells like rancid varnish. And you damn sure don’t want it in your carb or engine.

A few years ago I bought a 58 Chevy at auction. It had a 235 6cyl. I stopped and filled the tank for the drive home. (about 75miles). As I was filling up I could smell the bad gas. The car had been sitting a long time before the auction. It was running ok, not great, but ok. The farther I went the worse it got. I thought the fresh gas would help clear it up but no. By the time I got home it was barely running. I stopped in front of the house and it died. It was late so I went to bed. Next morning I tried to start it to put in my shop. It sounded like someone had pulled out all the spark plugs. Just spinning. After I pulled the engine out and removed the cover I found 8 bent pushrods!
The bad gas had gummed up the valves to the point that they stuck and bent the pushrods.

Today’s gas sucks! Buy non ethanol if you can find it. Or mix in some racing fuel or avgas.

Within a couple months of the Feds mandating ethanol gas in Atlanta 12+ years ago, the diaphragm in the original fuel pump in my '56 Cadillac swelled up and pumped only half the required amount of fuel.

Fortunately, I drive my vehicles all the time so gasoline doesn't get a chance to sit around in them and cause trouble. I get non ethanol when I can but living intown makes it somewhat difficult.

Even my '79 F 100 starts suffering from vapor lock on hot days due to the higher volatility of ethanol. That's a problem that was pretty much licked by 1979. Not anymore.

I also like the smell of stale gas (real gas). It's the basis of the classic "old car smell".
